bos_removekey - Removes a server encryption key from the KeyFile file
bos removekey -server <machine name> -kvno <key version number>+ [-cell <cell name>] [-noauth] [-localauth] [-principal <authentication principal> [-encrypt [<yes|no>]] [-config <configuration file>] [-help]
The bos removekey command removes each specified encryption key from the /etc/yfs/server/KeyFile file on the machine named by the -server argument. Use the -kvno argument to identify each key by its key version number; use the bos listkeys command to display the key version numbers.
Before removing a obsolete key, verify that the cell's maximum ticket lifetime has passed since the current key was defined. This ensures that no clients still possess tickets encrypted with the obsolete key.
Indicates the server machine on which to change the /etc/yfs/server/KeyFile file. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see bos(8).
In cells that use the Update Server to distribute the contents of the /etc/yfs/server directory, it is conventional to specify only the system control machine as a value for the -server argument. Otherwise, repeat the command for each file server machine. For further discussion, see bos(8).
Specifies the key version number of each key to remove.
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see bos(8).
Assigns the unprivileged identity
anonymous to the issuer.
Do not combine this flag with the -localauth flag.
For more details,
Constructs a server ticket using a key from the local /etc/yfs/server/KeyFileExt file. The bos command interpreter presents the ticket to the BOS Server during mutual authentication. Do not combine this flag with the -cell or -noauth options. For more details, see bos(8).
Indicates the principal to be used for authentication. This option can be useful when several credentials caches are available for different principals.
Enables or disables encryption for the command so that the operation's results are not transmitted across the network in clear text.
Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.
Prints the online help for this command. All other valid options are ignored.
The following command removes the keys with key version numbers 5 and 6 from the KeyFile file on the system control machine
% bos removekey -server fs1.example.com -kvno 5 6
The issuer must be listed in the /etc/yfs/server/UserListExt file on the machine named by the -server argument, or must be logged onto a server with an account capable of reading the /etc/yfs/server/KeyFileExt file if the -localauth flag is included.
